Battery For Compaq Laptop Computers

Bought for an old Compaq Presario to power the speakers on a monitor.....does the trick.

I have used several types of laptop computers, but Microsoft Surface Pro 7 is more than I expected :)

I bought for an old trackball Compaq Presario mouse that wasn't wore out.....nice size, does the job, excellent price.

Good little card reader for Laptop computers, but currently have not had the chance to try it out to see if it works good and how long it will last.

Used on a rather old HP/Compaq 6503 mini tower. Tried Crucial sticks with same specs but the machine balked. These worked fine. No idea why.

It's great, powerful and little noisy, it comes with good collection of attachments which will help you to clean every part of you computers, laptop, carpets, it can be use as vacuum or blower. The price is ok with what you will get

Heat is the #1 killer of laptop computers. I can run my laptop all day long and it stays nice and cool.

I use the Arc Mouse for my desktop, laptop and netbook computers. Very easy to use and the design makes it very comfortable to use. It takes just a little adjustment after switching from an optical mouse, but you will not go back.

Both dives allow me to easily transfer files from my laptop to my desktop computers. I find it very easy to use.

Short review: I wanted to find a USB switcher I didn't have to worry (or even think) about at all. This is it. Long review: for context for the rest of this review, my use case is to switch a common set of USB devices (keyboard, mouse, and USB audio device) between a desktop and a laptop. I bought this unit after having a poor experience with a much cheaper USB sharing switch from another manufacturer. This other unit lasted about two years, then started to fail to switch between host computers, and also seemed to be allowing voltage from one host to pass through to the other. I'm not one to risk damage to the valuable computers I've got hooked up to these switches. I got rid of that unit, did some research, and picked this one up based on some other folks' recommendations. This unit isn't cheap, and seems to be marketed primarily toward business use cases, but so far it's working perfectly for my home office setup. It appears that I'm getting exactly what I hoped I was paying for: reliability and safety. I haven't had a single electrical gremlin show up since I began using this. It automatically switches the three USB devices to my laptop when I plug it in, and switches back to the desktop when I unplug my laptop. I'd recommend reading the instructions and making use of the power supply.
